Singers, take note: if you want your music video to go viral, just ask Harry Styles and his One Direction bandmates to take off their shirts and dance in front of a camera. That's the formula behind Jason Derulo's clip for his new single, "Talk Dirty." At about two seconds into the video, Niall Horan shows off his moves in boxer briefs. It's not long until Harry, Zayn Malik, and Liam Payne join him. Robin Thicke, Ariana Grande [1], and Larry King also make (clothed) appearances. See all the action for yourself in the video below!
